Bank robberies are quite common. The average haul in a bank robbery is less than $5,000. [That’s down from almost $20,000 40 years ago.] 80%+ of all bank robberies are committed by repeat offenders. While it’s unusual to immediately catch someone involved in an individual robbery, most robbers ultimately get caught because they keep going until they get caught. So, most robbers are ultimately caught, but it generally takes several robberies before they actually get caught.
